Product Overview
RA33H1516M1‑501 is a 2‑stage VHF RF power amplifier module from Mitsubishi Electric, covering 154‑162 MHz for 12.5V mobile radio. It delivers ≥33W output with built‑in 50‑ohm matching. H57(H2M) metal‑ceramic flange‑mount package ensures good heat dissipation and VSWR ruggedness for land‑mobile and marine radio transmitters.
Core Advantages
High Power & Efficiency
≥33W output within 154‑162 MHz; typical 55% drain efficiency, low heat generation.
50‑Ohm Integrated Matching
On‑board input‑output impedance matching, no external tuning circuits required.
VGG Power Adjustment
0‑5V gate voltage control, compatible with APC automatic power‑control.
Reliable Mechanical Design
H57 flange‑mount package with strong VSWR tolerance for harsh field operation.

Frequently Asked Questions
Q1: What operating frequency range is covered by the RA33H1516M1‑501?
A: Tuned for 154‑162 MHz VHF band, suitable for land‑mobile and marine radio transmitters.
Q2: Does RA33H1516M1‑501 need external impedance‑matching circuit?
A: No. Built‑in 50‑ohm matching for input & output port, connect directly to 50‑ohm PCB trace.
Q3: What does suffix‑501 stand for? What is the difference between RA33H1516M1,‑501 and‑201?
A: Same die and H57(H2M) package. RA33H1516M1 is non‑RoHS base version.‑501 is standard RoHS grade.‑201 is RoHS with tighter RF bin‑sorting for mass production. All are pin‑to‑pin compatible.
Q4: How to adjust output power for this RF amplifier module?
A: Adjust VGG gate voltage 0‑5V, compatible with APC automatic power‑control circuits.
Q5: What is its package type and mounting requirement?
A: H57(H2M) metal‑ceramic flange package. Fasten firmly to heatsink for proper heat dissipation.
Q6: Are there cross‑reference alternative amplifier modules?
A: RA30H1317M1 can be referenced for lower‑power VHF application. Not direct drop‑in replacement; verify specs before design‑in.
Q7: Any special handling note for RA33H1516M1‑501?
A: It is ESD‑sensitive device. Apply ESD protection during assembly to prevent permanent damage.
Q8: How can I get datasheet and bulk quotation?
A: Submit your demand via Quick Inquiry form for datasheet, application note and volume pricing.
